Simply put, a virtual machine is the virtualization of a standard computer system. It relies on software instead of physical computer parts to operate. Multiple virtual machines can run on one host.
While many users are aware of their basic features, they’re unsure about their safety. You might be wondering if you can get a virus from a virtual machine.
Let’s find out!

Can you get a virus from joining a virtual machine?
Yes, you can get a virus from joining a virtual machine. Some malware types are sophisticated enough to migrate to the host computer.
You can accidentally download a virus while virtually browsing, for example. However, the problematic file will first try to infect the virtual machine’s system.
Then, if the host computer is in constant communication with that system, the virus may spread to it as well.
It’s important to keep in mind that not all viruses and malware can do this. Some will only infect the virtual machine system without migrating to the host.
What are the potential threats?
The two biggest threats that can endanger your host computer are:
- Malware that spreads automatically
- Malware from shared files.
Let’s take a better look at each type.
Malware that spreads automatically
This threat doesn’t require any type of manual action after you download the file. Once it gets on your virtual machine system, it can travel to the host computer.
For example, worms are entirely independent and don’t require human activation.
Malware is commonly transmitted via shared files.
Let’s say you download something using your virtual machine. If you move that file to the host computer, there’s a chance that you’ll bring along something malicious. Depending on what is attacking your computer, you may not even be able to notice it at first.
These types of threats can also move through shared clipboards.
How to avoid getting a virus from a VM?
Since it’s possible to get a virus from a virtual machine, you’ll have to be careful not to infect your host PC. Luckily, here are some easy strategies to ensure nothing gets on it:
Use a reliable program
There are various virtual machine programs available. In order to keep your computer virus-free, it’s important to stick to reliable options.
VirtualBox and VMWare are some of the biggest names available, and you can’t go wrong with either.
Create a new IP address
If you want to stay safe, creating a separate IP address for your virtual machine can help. This strategy is effective against malware that tries to spread via your home network.
Just remember that a new IP address is useless if you’re manually moving files between the virtual machine and the host.
Check disk partitioning
As mentioned above, keeping files from your virtual machine separate will protect your computer. You’ll have to properly partition your hard drive to do so.
If you’re using a high-end virtual machine program, it’ll take automatically take care of this. Other options may require manual configuration.
Summary
So, can you get a virus from a virtual machine? Unfortunately, yes, it’s possible. Malicious files can infect the host computer.
But now you also know a few new tricks to avoid this fate. As long as you use a reputable program and keep your files separate, you should be fine. Good luck!
